May Gardening Tips 🌿
1. Improve Drainage
Heavy winter rain can cause waterlogged soil. Add compost and avoid compacted beds.
2. Protect Young Seedlings
Cold nights and heavy rain can damage delicate seedlings. Use mulch or light protection where needed.
3. Feed Your Soil
Autumn and winter are perfect for building healthy soil with compost, worm castings, and organic matter.
4. Watch for Snails
Moist conditions bring snails and slugs. Check seedlings regularly.
5. Plant in Full Sun
Winter sun is gentler, so place vegetables where they’ll receive maximum sunlight.
The Western Cape winter garden can be incredibly productive with the right crops and timing. A little planting now means fresh harvests, colourful flowers, and healthy soil throughout the colder months. 🌱
